Motor mounts engine lift error!
I made a mistake in my MM procedure - the mount brackets have 17mm and 13mm bolts on each side, securing them to engine block.
I had loosened the lower mount 19mm nut to cross member, but didn't realise each mount had 17mm and 13mm bracket bolts on each side (so 4 of each size bolt in total for two mounts). I only removed one lot of 17mm and 13mm bolts from each mount before lifting the engine 1" using hoist from above.
I realised error when I was under car after the lift. So I lowered engine again and took out the remaining mount bolts on each side.
What I don't understand is that the engine lifted relative to cross member, but if each mount bracket was attached to block, and loosely bolted to cross-member, how did the engine manage to move relative to cross-member? I wondered if lifting when mounts still attached to block might have distorted the brackets holding the mounts? Any theories on what happened and consequences of my error?
Thanks

no worries.
what happened is that you lifted the mounts back to the uncompressed position.
NOTE be careful lifting the engine,
its easy to damage the oil fill spout on the cross bar strut,
or the HCV or FPR on the fuel cooler line

Thanks Stan that's a relief - lot of movement possible in those mounts.
I'm watching the rear of engine and the cooler line carefully when I lift - seems fair amount of clearance. I took cross strut off to position the lifting bar.
